Answer:

Step-by-step explanation:

f(X)= 7-2x

f(3) means u have to put the value of 3 in the given equation so it will be

= 7-2×3

= 7-6

= 1

and now you have to add 6 to it so it will be 7.

Determine whether each equation is True or False. In case you find a "False" equation, explain why is False.

elixir [45]

Answer:

(1) TRUE.

(2) FALSE.

(3) FALSE.

(4) TRUE.

(5) FALSE.

Step-by-step explanation:

(1) $\sqrt{32} = 2^{\frac{5}{2} }$

$2^{\frac{5}{2} } = (\sqrt{2} )^5 = (\sqrt{2} \ \times \ \sqrt{2} \ \times \ \sqrt{2} \ \times \ \sqrt{2} \ \times \ \sqrt{2}) = 4\sqrt{2}\\\\\sqrt{32} = \sqrt{16 \ \times \ 2}\ = \ \sqrt{16} \ \times \ \sqrt{2} \ = \ 4\sqrt{2}$

Thus, the equation is TRUE.

(2) $16^{\frac{3}{8} } = 8^2$

$16^{\frac{3}{8} } =(2^4)^{\frac{3}{8} } = 2^\frac{3}{2} }= (\sqrt{2} )^3 = (\sqrt{2} \ \times \ \sqrt{2} \ \times \ \sqrt{2}) = 2\sqrt{2} \\\\8^2 = 64$

Thus, the equation is FALSE.

(3) $4^{\frac{1}{2} } = \sqrt[4]{64}$

$4^{\frac{1}{2} }= \sqrt{4} = 2\\\\\sqrt[4]{64} = (64)^{\frac{1}{4} } = (2^6)^{\frac{1}{4} }= 2^{\frac{6}{4} } = 2^{\frac{3}{2} }=(\sqrt{2} )^3 = (\sqrt{2} \times \sqrt{2} \times \sqrt{2} ) = 2\sqrt{2}$

Thus, the equation is FALSE.

(4) $2^8 = (\sqrt[3]{16} )^6$

$2^8 = 256\\\\ (\sqrt[3]{16} )^6 = (16)^{\frac{6}{3} } = (2^4)^{\frac{6}{3} } = (2)^{\frac{24}{3} } = 2^8 = 256$

Thus, the equation is TRUE.

(5) $(\sqrt{64} )^{\frac{1}{3} } = 8^{\frac{1}{6} }\\\\$

$8^{\frac{1}{6} } = (2^3)^{\frac{1}{6} } = 2^{\frac{3}{6} } = 2^{\frac{1}{2} } = \sqrt{2} \\\\(\sqrt{64} )^{\frac{1}{3} } = (2^6)^{\frac{1}{3} } = 2^{\frac{6}{3} } = 2^2 = 4$

Thus, the equation is FALSE.

HURRY!!! PLEASE HELP WITH QUESTIONS!!!! WILL MAKE BRAINIEST ANSWER!!!!

Answer:

#1) D.$623.52 ; #2) D.17.1 ; #3) B.II and III ; #4) C.A greater availability of ATM's may make it easier to do bank transactions. Someone may choose this availability over a higher savings interest rate; #5) B.Bank E offers you a chocolate bar for filling out an application for checking and credit at the same time; #6) D.Make purchases or get cash now, and pay back the bank in monthly payments; #7) T; #8) B.Thursday ; #9) B.$1,545.83

Step-by-step explanation:

#1) 6.2% of her gross pay would be

0.062(765) = $47.43.

1.45% of her gross pay would be

0.0145(765) = 11.09

22% of the state tax withheld would be

0.22(68) = 14.96

This means her gross pay would be

765-68-47.43-11.09-14.96 = $623.52

#2) The employee benefits in addition to his gross pay would be

33500-28600 = 4900

This makes it

4900/28600 = 0.17 = 17% of his pay.

#3) Knowing where branches or ATMs are is helpful when choosing a bank. Additionally knowledge of personal usage habits and needs will help plan where best to bank.

#4) Having more ATMs available makes banking more convenient to some customers, which is more important to some customers than high interest rates.

#5) Having a chocolate bar offered for filling out an application for checking and credit is not a good reason to examine that given bank.

#6) You cannot "borrow" against a traditional checking account and then pay it back later.

#7) An ATM withdrawal is a POS (point of sale) transaction.

#8) At the end of the day Monday, Elizabeth has

252-114.6+150 = $287.40

At the end of Tuesday she has

287.40-79.68 = $207.72

At the end of Wednesday she has

207.72-161.39 = $46.33

At the end of Thursday she has

46.33-57.40 = -11.07

This is her first overdraft.

#9) Adding together the list of items deposited we have

13.50+942.06+75.53+670.14 = 1701.23

Taking out the cash he receives gives us

1701.23-155.40 = $1545.83
